i can confirm the watch has carcoal dial of course. i had two watches, both from swiss source:watchmaker for heuer and both 5012 movement.

same as described in caliber11 report.

as you say this is a 5100 variant movement. wirh the sence of having no 24 hr part.

: In Lemania Breguet group Heuer was the top level brand... so... why
: they use an entry level movement when they use in all 2 register
: chrono the 5100 without the 24H wheel.

: I never seen an Heuer 1000 with 5012 movement.

: But I saw a 3 register 1000 Series with 5012... andi it's
: impossibile.

: Maybe these watches were repaired changing movement in a second
: time?

: I think so...
